Video here: (32) SolderSmoke Podcast 243 (video) Hi7/N2CQR, uBITX, Success with High School Receiver Project - YouTube
Pete N6QW had technical difficulties this morning. He insisted that the show must go on. Pete will be back for the next episode.
Travelogue:
Bill in the Dominican Republic for all of January.
HI7/N2CQR Eastern
tip of the island. uBITX and dipoles.
20, 17, 10. CW and
SSB. SSB was tough and I had reports of
RF getting into the signal.
Went to CW.
Worked VWS Mike KA4CDN, and Walter KA4KXX on 20CW.
Finally moved up to 10 CW. Lots of contacts. Even though uBITX very QRP
on ten.
I am modifying the uBITX now.
Copper tape shielding to keep RF out.
Low power out not
the fault of the IRF-510s. The problem
is the 2N3904s.
Will replace with 2N2222 in To-18 cans.
Dean KK4DAS putting KD8CEC software into Arduino. I gave up.
Who sent me this orphan uBITX?
SolderSmoke Shack South in final phase of construction.
SHAMELESS COMMERCE DIVISION:
Patreon!
Bezos Shopping!
DC Receiver Project
Local High School radio club.
Simple: Like
Herring Aid 5 and Wes’s original.
Farhan’s four
stages:
BP Filter, Diode Ring, PTO, AF amp.
Simple Colpitts PTO SURPRISINGLY STABLE.
Simple and easy.
No chips. No complicated circuits.
Guys have helped test out the design: Rick N3FJZ, Walter KA4KXX,
Daniel VE5DLD, Stephen
VK2BLQ and others.
First session last night: We demonstrated build of the PTOs.
They worked (thank God).
